A random sample of 52 mothers and infants from a rural area of Northern Thailand were studied in their homes for 48 h. Infants were breast fed on demand. Daytime feeds were test weighed with electronic averaging balances and nighttime intake estimated using a new method, Indirect Test Weighing. All feeds, both day and night, were timed to the nearest minute. Other variables measured by direct observation were infant weight, and supplementary food and water intake. Mean 24-h breast milk intake was 579 g (range 78-1,011 g) with a median between day coefficient of variation of 8.8%. The proportion of 24-h breast milk intake consumed at night ranged from 8 to 91%, and increased with increasing infant age. Significant positive associations were found between breast milk intake, and sucking time and infant weight. There were significant negative associations between breast milk intake and age, and supplementary food and water intake.
对来自泰国北部农村地区的52对母婴进行了随机抽样，并在其家中进行了48小时的研究。婴儿按需母乳喂养。白天的喂奶量用电子平均天平进行测试称重，夜间摄入量则使用一种新方法——间接测试称重法进行估算。白天和夜间的所有喂奶时间都精确到分钟。通过直接观察测量的其他变量包括婴儿体重、辅食和水分摄入量。24小时母乳平均摄入量为579克（范围为78 - 1011克），日间变异系数中位数为8.8%。夜间摄入的24小时母乳量所占比例在8%至91%之间，且随婴儿年龄增长而增加。母乳摄入量与吸吮时间和婴儿体重之间存在显著的正相关。母乳摄入量与年龄、辅食和水分摄入量之间存在显著的负相关。
